Description
Summary
SSRF via Unguarded Configured Base URLs in Multiple Channel Extensions (Incomplete Fix for CVE-2026-28476)
Affected Packages / Versions
- Package:
openclaw - Affected versions:
<= 2026.3.24 - First patched version:
2026.3.25 - Latest published npm version at verification time:
2026.3.24
Details
Several channel extensions still used raw fetch() against configured base URLs without the SSRF guard that was added for CVE-2026-28476. Commit f92c92515bd439a71bd03eb1bc969c1964f17acf routes those outbound requests through fetchWithSsrFGuard so configured endpoints cannot be rebound to blocked internal destinations.
Verified vulnerable on tag v2026.3.24 and fixed on main by commit f92c92515bd439a71bd03eb1bc969c1964f17acf.
